/**
* This will generate the multisell list for the items.<br>
* There exist various parameters in multisells that affect the way they will appear:
*
* <ol>
* <li>Inventory only:
* <ul>
* <li>If true, only show items of the multisell for which the "primary" ingredients are
* already in the player's inventory. By "primary" ingredients we mean weapon and
* armor.
* <li>If false, show the entire list.
* </ul>
* <li>Maintain enchantment: presumably, only lists with "inventory only" set to true should
* sometimes have this as true. This makes no sense otherwise...
* <ul>
* <li>If true, then the product will match the enchantment level of the ingredient.<br>
* If the player has multiple items that match the ingredient list but the enchantment
* levels differ, then the entries need to be duplicated to show the products and
* ingredients for each enchantment level.<br>
* For example: If the player has a crystal staff +1 and a crystal staff +3 and goes
* to exchange it at the mammon, the list should have all exchange possibilities for
* the +1 staff, followed by all possibilities for the +3 staff.
* <li>If false, then any level ingredient will be considered equal and product will
* always be at +0
* </ul>
* <li>Apply taxes: Uses the "taxIngredient" entry in order to add a certain amount of adena to
* the ingredients.
* <li>
* <li>Additional product and ingredient multipliers.
* </ol>

* @param player
* @param npc
